The SDL_pulseaudio_hack.sh in the SDL-1.2.12-5.fc8 RPM doesn't work when you use
more then architecture (e.g. i386 and x86_64), the problem is this line in the
script:

[ -e /usr/lib*/alsa-lib/libasound_module_pcm_pulse.so ] && export
SDL_AUDIODRIVER=esd

This line gets two results for
"/usr/lib*/alsa-lib/libasound_module_pcm_pulse.so" when you install the 32bit
and the 64bit version of the "alsa-plugins-pulseaudio" RPM (for example skype
needs the 32bit alsa-plugins-pulseaudio RPM on a 64bit system) and when you get
more then two results the scripts fails with the message (every single time you
open a shell):

bash: [: /usr/lib64/alsa-lib/libasound_module_pcm_pulse.so: binary operator expected

I changed the line to this:

[ -e /usr/lib64/alsa-lib/libasound_module_pcm_pulse.so -o -e
/usr/lib/alsa-lib/libasound_module_pcm_pulse.so ] && export SDL_AUDIODRIVER=esd

this way it works at least for i386 and x86_64.
